Major character who has only appeared on 1 page in the entire OOTS saga

[ElderSage]

Has anyone said this one, yet?

There's lots of theories floating around about what happens to planar travelers and leftovers from other planes. We do, however, know that an ascended god can theoretically survive past their first world if they have enough stores of power between worlds. So...

These guys are using quiddity.

As far as I can tell, each of them, besides soda and pizza, has only appeared once, in that first comic. So, it could be Milk Dud(e)s, Nachos, Popcorn, or Soy Latte. Nachos and Milk Dud(e)s are both dead, so it's probably not them. Soy Latte wasn't shown using quiddity. But...

Popcorn has only appeared once. Popcorn was also shown using yellow quiddity, the color of the Northern Pantheon, who have been playing a very critical role.

My theory? Popcorn is going to come back.
